The radiant energy of the human eardrum mainly comes from the 6~15μm area.Ear thermometers usually use a thermopile sensor, which contains the above-mentioned optical system, photodetector-thermopile, thermistor.The thermopile sensor detects the far-infrared radiation intensity of the human eardrum

The ear thermometer is a non-contact telemetry (although it may be less than one centimeter) temperature measurement instrument. It uses the infrared spectrum emitted by the eardrum (equivalent to the hypothalamus) to determine the body temperature. According to the black body radiation theory, it i
